Patent CA-2256629-C (CA)

Abstract: In a process for the quantitative optical analysis of fluorescently labelled biological cells 5, a cell layer on a transparent support at the bottom 2 of a reaction vessel 1 is in contact with a solution 3 containing the fluorescent dye 4. The sensitivity of analytical detection can be considerably improved if to the fluorescent dye 4 already present in addition a masking dye 9, which absorbs the excitation light 6 for the fluorescent dye 4 and/or its emission light 7, is added to the solution 3 and/or if a separating layer 10 permeable to the solution and absorbing and/or reflecting the excitation light 6 or the emission light 7 is applied to the cell layer at the bottom 2. This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. The separating layer 10 must in this case be composed such that it has a high power of reflection for the luminescent light 11. Analogously, these process principles can also be used in receptor studies for the masking of the interfering background radiation in the quantitative optical analysis of fluorescently or luminescently labelled reaction components. In this case, a receptor layer 12 at the bottom 2 of a reaction vessel 1 is in contact with a solution (supernatant 3) in which a fluorescent or luminescent ligand 13 is dissolved. The sensitivity and accuracy of the analytical detection can be considerably improved here if a masking dye 9 which absorbs the excitation light 6 for the fluorescent dye and/or its emission light or (in the case of luminescent ligands) the luminescent light is added to the supernatant 3. Instead of the masking dye in the solution 3 or optionally as an additional measure, a separating layer 10 permeable to the solution 3 and absorbing and/or reflecting the excitation light 6 and/or the emission light or the luminescent light can be applied to the cell or receptor layer 12 at the bottom 2.

Abstract: A beam sharpened, low sidelobe antenna is obtained by segmenting the antenna to provide two sub-antennas (13, 15), one of which is arranged as an interferometer (15a, 15b). The output signals of the two antennas are added and subtracted to provide sum and difference signals (17). The sum and difference signals and the output signals are then utilized to provide the desired beam sharpened, low sidelobe antenna (22, 24).

Abstract: A microscope slide dispenser is formed with a slide case dispensing attachment having a slide dispensing mechanism and a disposable, plastic slide case that is removably coupled to the dispensing attachment. Positioning members on the dispensing attachment interact with corresponding members on the case to properly position the slide relative to a seating platform or slide case seat. A slide carrier has a anger that projects outwardly from the dispensing attachment and toward the slide case to engage the rear edge of the closest of a plurality of microscope slides stacked within the case. The case is provided with a carrier finger opening and a slide dispensing slot. Operation of the dispensing mechanism engages the carrier finger behind the slide closest to the end wall at which the dispensing attachment is located. The carrier finger pushes the microscope slide closest to the end wall at which the dispensing attachment is located out of the slide case through the slide dispensing slot. The carrier may be spring-biased so that the slide-engaging finger returns to a slide-engaging position behind the next slide, which moves into place once the slide aligned with the slide ejection slot has been ejected. Once all slides have been ejected from the case, the case is discarded.

Abstract: In a drive system for a mail processing machine a comparatively simple and clear design of the driving tracks and of the bearings for the respective shafts is obtained by feeding drive energy from a common drive motor to a bevel gear drive and a step gear drive. Thereby, the output shafts of the bevel gear drive and the step gear drive have identical sense of rotation because of the sense of rotation reversal within the respective gear drive. The bevel gear drive, at its output, provides a continuous rotation, and the step gear drive provides an intermittent rotation. From the output shafts of the bevel gear drive and of the step gear drive, respectively, driving connections can be led to the driving shafts for a continuously moved conveyor chain for documents and to an intermittently moved conveyor chain for documents, respectively.
